Description

本発明は、車両と外部要素との間の衝突に起因する衝撃中に、エネルギーを分散させるための、「バンパー」として知られているシステムをもつエネルギーリザーバを備える車両に関する。車両は、たとえば、電気推進自動車またはハイブリッド推進自動車であり得る。   The present invention relates to a vehicle comprising an energy reservoir with a system known as a “bumper” for distributing energy during an impact resulting from a collision between the vehicle and an external element. The vehicle can be, for example, an electric propulsion vehicle or a hybrid propulsion vehicle.

より詳細には、本発明は、車両床の下に載置されたバッテリー、あるいはガスタンクまたは燃料タンクなどのエネルギーリザーバを備える車両に関する。   More particularly, the present invention relates to a vehicle equipped with an energy reservoir such as a battery or gas tank or fuel tank mounted under the vehicle floor.

車両の支持構造が受ける損傷をできる限り小さくなるように、今日、車両と外部要素との間の衝突によって放出された衝撃エネルギーを吸収するために、車両の前部および後部にバンパーシステムが取り付けられているのが標準的である。   Bumper systems are now installed at the front and rear of the vehicle to absorb the impact energy released by collisions between the vehicle and external elements so that the damage to the vehicle support structure is minimized. It is standard.

バンパーシステムは、一般に、衝撃エネルギーを変形力に変換する衝撃アブソーバなどの構成要素と、衝撃から生じたエネルギーを衝撃アブソーバに伝達することができるクロスメンバーとを備える。これらのバンパーシステムは、フロントビームまたはリアビーム上のできる限り中央に衝撃アブソーバが載置されるように、かつ、衝撃エネルギーが衝撃アブソーバに、したがってフロントビームまたはリアビームにも伝達されるように設計される。   A bumper system generally includes components such as an impact absorber that converts impact energy into deformation force, and a cross member that can transmit energy generated from the impact to the impact absorber. These bumper systems are designed so that the impact absorber is mounted as centrally as possible on the front or rear beam and that the impact energy is transmitted to the impact absorber and thus also to the front or rear beam .

エネルギー分散システムは、有効な様々な規格、および新しい車両の設計に関連する様々な要件に絶えず適合し直さなければならない。特に、電気自動車またはハイブリッド自動車が出現したとき、衝撃中のバッテリーに対する熱的および電気的リスクを低減するために、バッテリー保護規格が確立された。車両床の下にバッテリーを設置するためには、バッテリーに対する損傷を制限するために、側面衝撃中にエネルギーを分散させるためのシステムを設計することが必要である。   The energy distribution system must continually adapt to the various standards that are valid and the various requirements associated with the design of new vehicles. In particular, when electric vehicles or hybrid vehicles have emerged, battery protection standards have been established to reduce the thermal and electrical risks to batteries under impact. In order to install the battery under the vehicle floor, it is necessary to design a system for distributing energy during side impacts in order to limit damage to the battery.

したがって、本発明の目的は、車両床の下に載置されたエネルギーリザーバに対する損傷の危険性を最小限に抑えるために、横方向に最適化されたエネルギー分散システムを備える、車両床の下に載置されたエネルギーリザーバを備える車両、特に、電気推進車両またはハイブリッド推進車両を提供することである。   Accordingly, it is an object of the present invention to provide an underside vehicle floor with a laterally optimized energy distribution system to minimize the risk of damage to an energy reservoir mounted underneath the vehicle floor. It is to provide a vehicle, in particular an electric propulsion vehicle or a hybrid propulsion vehicle, with a mounted energy reservoir.

一実施形態では、本発明は、車両床の下に載置されたエネルギーリザーバ支持体、たとえばバッテリーのバンクを備える車両に関する。エネルギーリザーバ支持体は、車両の側方サイドメンバー間に固定される。サイドメンバーは、車両の長手方向に配列された車両シャーシの一部である。本車両は、それの床の下または上に、車両の対称軸に関して対称的である２つのサイドメンバーを有する。   In one embodiment, the invention relates to a vehicle comprising an energy reservoir support, eg, a bank of batteries, mounted under the vehicle floor. The energy reservoir support is secured between the side side members of the vehicle. The side member is a part of the vehicle chassis arranged in the longitudinal direction of the vehicle. The vehicle has two side members that are symmetrical about the axis of symmetry of the vehicle below or above its floor.

本車両は、車両の外側車体とバッテリーなどのエネルギーリザーバとの間の車両フロアの下にある空間への挿入することができる側面衝撃を吸収するための手段を備える。衝撃吸収手段は、衝撃エネルギーを分散させることを可能にする変形可能な構造の形態をとる。車両の外側車体構造は、一般に車両の下側本体と呼ばれる。   The vehicle comprises means for absorbing side impacts that can be inserted into a space under the vehicle floor between the vehicle's outer body and an energy reservoir such as a battery. The shock absorbing means takes the form of a deformable structure that allows the shock energy to be dispersed. The outer body structure of the vehicle is generally called the lower body of the vehicle.

有利には、衝撃吸収手段は、エネルギーリザーバ支持体の両側に載置された主側方アブソーバおよび側方プレートを備える。   Advantageously, the shock absorbing means comprises a main side absorber and a side plate mounted on both sides of the energy reservoir support.

たとえば、各側方プレートはエネルギーリザーバ支持体に固定され、主側方アブソーバは、各サイドメンバーとエネルギーリザーバ支持体との間に載置される。   For example, each side plate is fixed to the energy reservoir support, and the main side absorber is placed between each side member and the energy reservoir support.

衝撃吸収手段は、車両の外側車体と主側方アブソーバとの間に載置された少なくとも１つの副側方アブソーバを備えることができる。   The impact absorbing means may include at least one auxiliary side absorber placed between the outer body of the vehicle and the main side absorber.

有利には、副アブソーバは、側方プレートの各々に固定される。   Advantageously, a secondary absorber is fixed to each of the side plates.

本車両は、エネルギーリザーバ支持体を補強するための手段を備える。これらの補強手段は、主側方アブソーバの各々に固定することができる少なくとも１つの水平なクロスメンバーを備える。   The vehicle includes means for reinforcing the energy reservoir support. These reinforcing means comprise at least one horizontal cross member that can be secured to each of the main side absorbers.

さらに、側方プレートは、サイドメンバーのうちの１つに固定することが可能であり、スタンプ加工された金属シートを備える。   Further, the side plate can be secured to one of the side members and comprises a stamped metal sheet.

主側方アブソーバおよび副側方アブソーバは、合成材料または金属材料で作製することができ、衝撃時にエネルギーを分散させることが可能な構造、たとえば、セル状構造を有することができる。   The main side absorber and the sub side absorber can be made of a synthetic material or a metal material, and can have a structure capable of dispersing energy upon impact, for example, a cellular structure.

第２の態様によれば、本発明は、車両床の下に固定することが可能なエネルギーリザーバ支持体に関する。   According to a second aspect, the invention relates to an energy reservoir support that can be fixed under the vehicle floor.

本エネルギーリザーバ支持体は、側方プレートおよび主側方アブソーバを備える側面衝撃を吸収するための手段を備える。   The energy reservoir support comprises means for absorbing side impacts comprising a side plate and a main side absorber.

有利には、吸収手段は、車両の外側車体構造とエネルギーリザーバとの間の車両床の下にある空間に装着される。   Advantageously, the absorbing means is mounted in a space below the vehicle floor between the vehicle outer body structure and the energy reservoir.

添付の図面を参照しながら、非限定的な例として与えられた以下の説明を読むと、本発明のさらなる目的、特徴および利点が明らかになるであろう。   Further objects, features and advantages of the present invention will become apparent from the following description given by way of non-limiting example with reference to the accompanying drawings.

本発明による車両の断面図である。1 is a cross-sectional view of a vehicle according to the present invention. 断面線ＩＩ−ＩＩに沿った平面図である。It is a top view along section line II-II. 断面線ＩＩＩ−ＩＩＩに沿った側面図である。It is a side view along section line III-III.

図１に示される車両１は、たとえば、電気自動車またはハイブリッド自動車である。車両１のシャーシは、図示された例では、電池の貯蔵部であるエネルギーリザーバ３のための支持体２を備える。支持体２は、たとえば、ボルト（図示せず）を用いて側方サイドメンバー４に固定される。側方サイドメンバー４は、車両の長手方向に配列された車両シャーシの一部に対応する。支持体２は、車両１の床５の下に載置される。   A vehicle 1 shown in FIG. 1 is, for example, an electric vehicle or a hybrid vehicle. The chassis of the vehicle 1 includes a support 2 for an energy reservoir 3 that is a battery storage in the illustrated example. The support 2 is fixed to the side member 4 using, for example, bolts (not shown). The side member 4 corresponds to a part of the vehicle chassis arranged in the longitudinal direction of the vehicle. The support 2 is placed under the floor 5 of the vehicle 1.

車両１は、側面衝撃のエネルギーを吸収するための手段を備える。これらの吸収手段は、バッテリー３と車両の車体構造６との間の利用可能な空間中に挿入される。   The vehicle 1 includes means for absorbing side impact energy. These absorbing means are inserted into the available space between the battery 3 and the vehicle body structure 6 of the vehicle.

衝撃吸収手段は、支持体２の両側に載置された側方プレート７を備える。側方プレート７は、たとえば、溶接によって支持体２に固定することができる。これらの側方プレート７は、エネルギー吸収を向上させるために、押出成形された金属プレート、たとえば、アルミニウムまたは鉄鋼で作製することができる。それらは、側方サイドメンバー４の下に載置される。側方プレート７は、たとえば、ねじ接続を介して、または迅速な取外しおよび再取付けを可能にする任意の他のシステムによって車両構造に固定することができる。   The shock absorbing means includes side plates 7 mounted on both sides of the support 2. The side plate 7 can be fixed to the support 2 by welding, for example. These side plates 7 can be made of an extruded metal plate, for example aluminum or steel, to improve energy absorption. They are placed under the side member 4. The side plate 7 can be secured to the vehicle structure via, for example, a screw connection or by any other system that allows for quick removal and reattachment.

さらに、衝撃吸収手段は、支持体２の両側に載置された主側方アブソーバ８を備える。各主側方アブソーバ８は、各サイドメンバー４と支持体２との間に載置される。   Further, the impact absorbing means includes main side absorbers 8 placed on both sides of the support 2. Each main side absorber 8 is placed between each side member 4 and the support 2.

また、図示された例では、衝撃吸収手段は、側方プレート７の各々上に載置された２つの副側方アブソーバ９を備える。副側方アブソーバ９は、車両の外側車体構造６と主側方アブソーバ８との間に載置される。より正確には、外側車体構造６とサイドメンバー４の各々との間に副側方アブソーバ９を載置することができる。しかしながら、これらの側方アブソーバ９は、車両に応じた様々な場所に、また、支持体２と車両の外側車体構造６との間の利用可能な空間に載置することができる。必要に応じて、副側方アブソーバ９は、より少数または３つ以上とすることができる。   In the illustrated example, the impact absorbing means includes two sub-side absorbers 9 mounted on each of the side plates 7. The sub-side absorber 9 is placed between the outer vehicle body structure 6 and the main side absorber 8 of the vehicle. More precisely, the sub-side absorber 9 can be placed between the outer vehicle body structure 6 and each of the side members 4. However, these side absorbers 9 can be placed in various places depending on the vehicle and in the available space between the support 2 and the outer body structure 6 of the vehicle. If necessary, the number of secondary side absorbers 9 can be smaller or three or more.

主側方アブソーバ８および副側方アブソーバ９は、たとえば、スチールまたは押出しアルミニウムなどの金属材料、あるいはポリプロピレン（ＰＰ）などの合成材料で作製することができ、サイドメンバー４に直交する方向にセルが配向されたセル状構造（たとえば、ハニカム型）など、衝撃時にエネルギーを分散させることが可能な構造を有することができる。アブソーバ８および９の寸法は、支持体２の長さと、地面と車両１の床５との間に高さとに依存する。   The main side absorber 8 and the sub side absorber 9 can be made of, for example, a metal material such as steel or extruded aluminum, or a synthetic material such as polypropylene (PP), and the cell extends in a direction perpendicular to the side member 4. It can have a structure capable of dispersing energy at the time of impact, such as an oriented cellular structure (for example, honeycomb type). The dimensions of the absorbers 8 and 9 depend on the length of the support 2 and the height between the ground and the floor 5 of the vehicle 1.

車両１は、クロスメンバー１０を備える補強手段を備えることができる。これらのクロスメンバー１０は、ねじによって、または任意の他の手段によって主側方アブソーバ８の各々に固定される。   The vehicle 1 can include reinforcing means including the cross member 10. These cross members 10 are secured to each of the main side absorbers 8 by screws or by any other means.

図２に、図１の断面線ＩＩ−ＩＩに沿った車両１の平面図を示す。非限定的な例として、３つのクロスメンバー１０が存在する。支持体２を補強するために、クロスメンバー１０の数は、それらの厚さおよび必要に応じて変えることができる。   FIG. 2 is a plan view of the vehicle 1 taken along the sectional line II-II in FIG. As a non-limiting example, there are three cross members 10. In order to reinforce the support 2, the number of cross members 10 can be varied according to their thickness and as required.

図３に、図１の断面線ＩＩＩ−ＩＩＩに沿った車両１の側面図を示す。   FIG. 3 shows a side view of the vehicle 1 taken along section line III-III in FIG.

エネルギー分散システム１は、車両１の外側で支持体２上に取り付けられ、次いで、支持体２は、車両１の床５の下の利用可能な空間に衝撃吸収手段７、８および９を配置するようにサイドメンバー４に固定される。   The energy distribution system 1 is mounted on a support 2 outside the vehicle 1, which then places the shock absorbing means 7, 8 and 9 in an available space under the floor 5 of the vehicle 1. It is fixed to the side member 4 as follows.

衝撃吸収手段の位置および寸法は、各車両に適合させることができる。   The position and dimensions of the shock absorbing means can be adapted to each vehicle.

このようにして、第２の実施形態では、アブソーバ９は、たとえば、支持体に固定された側方プレート７にではなく、代わりに、下側本体またはクロスメンバー４などの車両の構造要素に固定され得る。アブソーバ８をクロスメンバー４に固定することも可能である。そのような実施形態は、エネルギーリザーバ、特に、横方向のバッテリーに必要な空間を低減するという利点を有する。   Thus, in the second embodiment, the absorber 9 is not fixed to the side plate 7 fixed to the support body, for example, but instead to the vehicle structural element such as the lower body or the cross member 4. Can be done. It is also possible to fix the absorber 8 to the cross member 4. Such an embodiment has the advantage of reducing the space required for an energy reservoir, in particular a lateral battery.

上記した本発明によって、車両の横方向の衝突中、車両エネルギーリザーバ、より詳細には、電気自動車またはハイブリッド自動車の場合には、バッテリー支持体中に含まれている１つまたは複数のバッテリーが保護される。衝突中、衝撃エネルギーは、エネルギー吸収手段および補強手段に伝達される。補強手段は次いで、衝撃エネルギーによって圧縮され、それにより、エネルギーリザーバが保護され、危険であると判明し得る劣化の危険性が予防される。   The present invention described above protects a vehicle energy reservoir, and more particularly, in the case of an electric or hybrid vehicle, one or more batteries contained in a battery support during a lateral collision of the vehicle. Is done. During the collision, the impact energy is transmitted to the energy absorbing means and the reinforcing means. The reinforcing means is then compressed by impact energy, thereby protecting the energy reservoir and preventing the risk of degradation that may prove to be dangerous.

上記し、各図に示された実施形態は、床の下の装着されたバッテリーを装備する車両に関する。本発明は、大きな修正を加えることなく、床の下のあるガスタンクまたは燃料タンクなど、他のタイプのエネルギー源に応用することができる。   The embodiments described above and illustrated in the figures relate to a vehicle equipped with a mounted battery under the floor. The present invention can be applied to other types of energy sources, such as a gas tank or fuel tank under the floor without major modifications.
